maybe I should just have a shop do this, has anyone else advanced their cams at all on this motor? were the results desirable? as far as I was told, for every 1 degree advanced, it shifts your RPM power band ahead by 100 rpm, so if your power band is 1200-4200, and you advance it 4 degrees, your new power band would be 800-3800, as far as I was told anyhow, so let me know if any of ya all have done this and what the results were.
